With the development of urbanization, cement concrete roads are laying more and more, and the requirements are getting higher and higher. The traditional leveling operation has the disadvantages of high labor cost, long time and poor precision. Based on this, a control system of cement concrete leveling based on laser sweeping technology is designed, and the cement concrete leveling control system based on the laser scanning level is designed. The embedded controller STM32 is used as the control core of the system, the laser horizontal plane scanned by the laser swinger is regarded as the horizontal standard of the leveling system. Two rows of laser receiving sensor arrays mounted on the scraping shovel were used to detect the vertical relative position and tilt of the scraping shovel. The stepping motor driving chip TB67S109AFTG was used to drive two stepping motors to realize the automatic adjustment of the vertical position and inclination of the scraping shovel, and realize the automatic leveling function of the laser leveling machine. Finally, the precision reached 4mm.
